Watermelon seed oil is extracted by pressing from the seeds of the Citrullus lanatus (watermelon). It is particularly common in West Africa, where it is also called ootanga oil.
The common watermelon most likely originated almost 5,000 years ago in the Kalahari Desert. Its wild ancestor, the Kalahari Melon, still grows there, and its seeds are pressed for their oil. Watermelons migrated north through Egypt, and during the Roman era they were cultivated and prized.[1]
Like their wild ancestors, modern domestic watermelon seeds can be pressed for oil. Traditionally, the seeds are extracted from the seed casing, and dried in the sun. Once dried, the seeds are pressed.
Watermelon seed oil contains high amounts of unsaturated fatty acids, primarily linoleic and oleic acids.[2]
| Fatty Acid | Percent |
|---|---|
| Palmitic acid (C16:0) | 11.0 |
| Stearic acid (C18:0) | 10.0 |
| Oleic acid (C18:1) | 15.0 |
| Linoleic acid (C18:2) | 63.0 |
| Refractive Index (40°C) | 1.4630-1.4670 |
| Iodine value | 115-125 |
| Saponification value | 190-198 |
| Unsaponifiable matter | 1.5% max |
| Moisture | 0.5% max |
| Colour 1/2" cell (y+5R) | 20.0 units |

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
